To determine the distance (d) traveled by a body given its speed (S) and the time (t). Use the equation,
S = d / t ; d = S x t
Substituting the known values to the equation,
d = (4 m/s ) x (40 s) = 160 m
Thus, the person will travel 160 meters in 40 seconds.
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
<h3>What is a heating curve?</h3>
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
The point A represents the steady increase in the temperature of the solid. The point B shows the point of fusion, at this point, the solid is transformed into liquid. The point C shows the temperature rise with time as the liquid is heated. The point D shows the process of vaporization which converts the liquid to gas. The point E shows when the substance now exists in the gas phase.

Answer:
As speed changes, wavelength and frequency change.
Explanation:
-Wave speed is related to both the wavelength and wave frequency as:
-Wavelength is measured in meters, frequency in Hertz(Hz) and speed in m/s.
-Increasing the wavelength of a wave decreases its frequency and therefore the wave speed will remain constant .
-As a such, the product of wavelength and wave frequency is still the same speed.
(if it's frictionless the length doesn't even matter :) )
It would have the same kinetic energy down as the potential energy up. That is,
or
(the mass doesn't even matter). The result is
, so only the height matters really. It is almost 9 (it is
).
